Libya's navy says 90 migrants perished after boat fell apart
CAIRO (AP) - The Libyan navy said on Thursday that at least 90 migrants are believed to have perished when their rickety boat started to fall apart in the Mediterranean Sea, after leaving the Libyan coast. The boat, which was made of rubber, tore and began filling with water about 42 kilometers (26 miles) off the Libyan coast, an area considered to be international waters, said the spokesman for the navy, Ayoub Gassim. The Libyan coast guard rescued 29 survivors, who recounted that there were 129 of them in all on the boat, mostly African nationals, Gassim said. The migrants left Tajoura, in western Libya, before dawn on Wednesday morning, and the coast guard received a call for help around 3 p.m.

Support for 'my girl' Clinton is personal, Mrs. Obama says
WINSTON-SALEM, N.C. (AP) - As first ladies they could hardly have been more different. But as Democrats looking to fire up female voters, Michelle Obama and Hillary Clinton were firmly bonded on Thursday. In their first joint appearance on the campaign trail, Mrs. Obama and Clinton talked up their shared respect, common values and singular goal: Defeating Republican Donald Trump. They papered over a somewhat rocky history and their vastly different paths through public life. With Mrs. Obama aiming to secure her husband's legacy and Clinton needing to propel women to the polls, the two women sought to celebrate their political marriage of mutual interest, and reassure voters it's real.

Police fire pepper spray, bean bags as they oust protesters
CANNON BALL, N.D. (AP) - Law enforcement officers dressed in riot gear fired bean bags and pepper spray on Thursday as they tried to clear protesters from a camp on private land in the path of the Dakota Access oil pipeline. North Dakota State Emergency Services spokeswoman Cecily Fong said the officers were responding to "aggressive" tactics by protesters, including some throwing rocks at officers and threatening them. A male protester was holding his leg after an Associated Press reporter at the scene described hearing a loud boom. A protester with a medic bag tended to the man's leg, and he was up and walking a short time later.

AP-GfK poll: Most Trump supporters doubt election legitimacy
CHARLOTTE, N.C. (AP) - Donald Trump's dubious claims the presidential election is "rigged" have taken root among most of his supporters, who say they will have serious doubts about the legitimacy of the election's outcome if Hillary Clinton wins, according to a new Associated Press-GfK poll. Just 35 percent of Trump's supporters say they will most likely accept the results of the election as legitimate if Clinton wins, while 64 percent say they're more likely to have serious doubts about the accuracy of the vote count if the Republican nominee is not the victor. "Of course I believe it's rigged, and of course I won't accept the results," said Mike Cannilla, 53, a Trump supporter from the New York borough of Staten Island.

Iraqis find bomb factory, tunnels on long road to Mosul
KHAZER, Iraq (AP) - Iraqi forces explored a network of tunnels and uncovered a bomb-making facility on Thursday in a village near Mosul that was recently retaken from the Islamic State group, offering a glimpse of the challenge they will face as they move closer to the city. Ten days into the offensive, the special forces are still at least 4 miles (6 kilometers) east of the city and have faced stiff resistance, with IS firing mortars and machine guns, and sending armored suicide truck bombs trundling across the arid plains. Once inside the small, sparsely populated villages that ring Mosul, Iraqi forces must contend with explosive booby-traps and hidden snipers.

UN says school attack in Syria may be potential war crime
BEIRUT (AP) - U.N. Secretary-General Ban Ki-moon called on Thursday for an immediate investigation of an attack on a school in Syria's Idlib province that the U.N.'s children's agency is calling one of the deadliest of its kind in the country's six-year war. UNICEF raised its toll for Wednesday's attack to 28 dead, among them 22 children and six teachers. Ban said in a statement that the attack, carried out against rebel-held territory, may amount to a war crime if found to be deliberate. "If such horrific acts persist despite global outrage, it is largely because their authors, whether in corridors of power or in insurgent redoubts, do not fear justice.

Health law consumers face least choice in program's history
WASHINGTON (AP) - Americans in the health insurance markets created by President Barack Obama's law will have less choice next year than any time since the program started, a new county-level analysis for The Associated Press has found. The analysis by AP and consulting firm Avalere Health found that about one-third of U.S. counties will have only one health marketplace insurer next year. That's more than 1,000 counties in 26 states - roughly double the number of counties in 2014, the first year of coverage through the program. With insurance notices for 2017 in the mail, families are already facing difficult choices, even weighing whether to stay covered.

Weed as way of life: California farmers divided on legal bud
GARBERVILLE, Calif. (AP) - Laura Costa's son and husband moved quickly with the pruning shears to harvest the family's fall marijuana crop, racing along with several workers to cut the plants and drop them in plastic bins ahead of an impending storm. The rain could invite "bud rot," Costa said, "a big no-no." The farm, hidden along a winding mountain road in a remote redwood forest, is just one of many illegal "grows" that make up Northern California's famous Emerald Triangle, a rural region that developed over decades into a marijuana-producing mecca at the intersection of Humboldt, Mendocino and Trinity counties.

Twitter cuts staff, kills off Vine app amid pressure to grow
NEW YORK (AP) - Twitter, seemingly unable to find a buyer and losing money, is cutting about 9 percent of its employees worldwide. It is also killing off Vine, a mobile video app where people share short video clips that play in a loop. While beloved by users and a pioneer in its own right, Vine, which launched in 2013, never took off with the masses and has lost its luster as of late. Twitter has failed to keep pace with rivals Facebook, Snapchat and Instagram and in recent months, rumors abounded that it would be acquired. In a conference call with analysts on Thursday, CEO Jack Dorsey quickly brushed aside what he called "recent market speculation." He said the company is committed to growing long-term shareholder value, and that he doesn't plan to comment "any further on this topic." Shares of Twitter, which have tumbled 27 percent in the past month as possible suitors have wandered away, rose 34 cents, or 2 percent, to $17.63 in afternoon trading on Thursday.

Mom says noose leaves life-changing emotional scar on son
WIGGINS, Miss. (AP) - A black 15-year-old in Mississippi shook in fear as he described how white schoolmates put a noose around his neck and pulled it tight, leaving no physical scars but perhaps a life-changing emotional wound, his mother said Thursday. Stacey Payton, a 47-year-old college instructor, said her son met her in her office and told her about the Oct. 13 incident a few hours after it happened in a high school locker room. "His first words were, 'Mom ... please stay calm. Don't panic. I don't want you to call the school because it's already been handled,'" Payton told The Associated Press.
